UccSubscriptionEvent is an abstract class and therefore, does not provide a callable constructor. To obtain an instance of the UccSubscriptionEvent, a client must handle the subscription events. The event data parameter of all three subscription events provides a client with an instance of the UccSubscriptionEvent class.


The following example handles the subscription OnUnsubscribe event and uses the provided UccSubscriptionEvent instance to provide a condition under which the IUccSubscription is unadvised.

void _IUccSubscriptionEvents.OnUnsubscribe(
    UccSubscription pEventSource, 
    UccSubscriptionEvent pEventData)
    if (pEventData.IsComplete == true)
        UCC_Unadvise<_IUccSubscriptionEvents>(pEventSource, this);
